A clogged range hood filter can make cooking smell linger, leave greasy film on nearby cabinets, and force your hood to work harder than it should. The good news is that replacing one is usually a quick job you can handle yourself—once you know which filter your hood needs and how it comes out.
Here’s how to replace a range hood filter in three straightforward steps, plus how to tell whether yours should be replaced or simply cleaned.

Why Your Range Hood Filter Matters
When you fry, sauté, or roast, cooking sends grease, smoke, and tiny food particles into the air. A range hood pulls that air through a filter before it moves outdoors or circulates back into the kitchen. The filter catches grease and, in some hood designs, helps reduce cooking odors.
A filter packed with grease can restrict airflow. That means smoke and odors may not clear as effectively, and grease can build up inside the hood. Cleaning or replacing the filter helps your range hood work as intended and makes kitchen cleanup easier.
Not every filter is designed to be replaced on the same schedule. Some are washable and reusable; others, especially charcoal filters in recirculating hoods, are meant to be replaced. Check your hood’s manual or model number before buying anything. A filter that looks close but has the wrong dimensions or attachment points may not fit securely.
Step 1: Identify the Filter and Buy the Right Replacement
Start by figuring out what type of filter your range hood uses. If you can find the manual, look for a section called “filter,” “maintenance,” or “replacement parts.” If the manual is missing, search online using the hood’s brand and model number. The model label is often under the hood, behind a filter, or inside the unit.
You can also remove the existing filter and inspect it. Do this only after the hood is switched off and cool. Note its shape, measurements, material, and how it attaches. Take a photo before removing it, especially if it has tabs, clips, or a specific direction it needs to face.
Know Which Kind of Filter You Have
| Filter type | What it does | Typical care |
|---|---|---|
| Aluminum or mesh grease filter | Traps grease while air passes through | Usually washable and reusable; replace it if damaged or still clogged after cleaning |
| Stainless steel baffle filter | Uses shaped metal channels to collect grease | Usually washable and reusable; check the manual for cleaning instructions |
| Charcoal or carbon filter | Helps reduce odors in many recirculating hoods | Usually disposable and replaced when saturated; most cannot be washed back to full effectiveness |
Many ducted range hoods use a metal grease filter and send air outside through ductwork. A recirculating hood filters the air and sends it back into the room; it may use both a metal grease filter and a charcoal filter. In that setup, the charcoal filter is often hidden behind the metal filter or attached near the fan. Replacing the metal filter alone won’t refresh a worn-out charcoal filter.
Check Fit Before You Order
Use the hood’s exact model number whenever possible. If you’re matching by size, measure the filter’s length and width, and check its thickness and attachment style too. A filter that is even slightly too small can leave a gap for grease to pass through. One that is too large may not lock in place.
Buy a compatible filter from the hood’s manufacturer or a reputable parts supplier. If you choose an aftermarket option, compare the listed model compatibility and return policy. Don’t rely on appearance alone: two filters can look similar while using different clips or having slightly different dimensions.
Step 2: Remove the Old Filter Safely
Turn the range hood off and let the cooktop and hood cool completely. If you’re replacing a filter near electrical parts or you’ll be reaching into the hood, switch off power at the wall or circuit breaker as an extra precaution. You generally don’t need to disconnect wiring for a filter change, so don’t remove panels or reach near the fan unless the manual specifically instructs you to.
Put a towel or paper towels on the cooktop to catch drips. Old filters can hold sticky grease, and metal edges may be sharp, so use gloves if you have them.
Release the Filter Without Forcing It
Most metal filters are held by a small latch, spring clip, or sliding track. Support the filter with one hand while you release the latch with the other. Some filters tilt down first and then slide out; others lift slightly before coming free. If it doesn’t move easily, pause and look for another clip rather than pulling hard.
For a charcoal filter, the metal grease filter may need to come out first. The carbon filter might twist onto the fan housing or clip into a frame. Check the manual or take a quick photo of the arrangement so you can install the new one in the same position.
Once the old filter is out, check the space around it. Wipe away accessible grease with a soft cloth and a suitable kitchen cleaner, following the hood maker’s cleaning advice. Avoid spraying cleaner into the fan, motor, lights, or electrical openings. If you see damaged wiring, a loose fan, or heavy grease deep inside the hood, stop and arrange appropriate repair or cleaning help.
Step 3: Install the New Filter and Test the Hood
Compare the old filter with the new one before fitting it. Check that the edges, tabs, and dimensions match. For charcoal filters, look for an airflow arrow or other direction marking and follow the instructions included with the replacement.
Slide or lift the filter into its track, then engage the clip or latch. It should sit flat and feel secure, with no obvious gaps. Don’t bend the filter to make it fit. If it won’t lock into place, remove it and check that you have the correct part and orientation.
After the filter is installed, restore power if you switched it off and run the hood on a low setting for a few seconds. Listen for rattling and check that the filter stays in place. If the hood sounds different, vibrates, or the filter slips, turn it off and reseat the filter before using it again.
Should You Replace the Filter or Clean It?
Metal mesh and baffle filters are often reusable. If yours is simply greasy, washing may be all it needs. Follow the manufacturer’s directions: some metal filters are dishwasher-safe, while others should be hand-washed. When hand-washing, soak the filter in warm water with dish soap or a degreasing cleaner suitable for the material, then rinse and let it dry completely before reinstalling.
Replace a reusable metal filter if it is bent, cracked, corroded, has a broken latch, or remains heavily clogged after cleaning. A damaged filter may not sit securely, and a clogged one can still limit airflow even if the outside looks clean.
Charcoal filters are different. They absorb odors rather than simply catching visible grease, and washing generally won’t restore their odor-reducing ability. Replace them according to the hood manual or when cooking smells continue to linger despite a clean metal filter and a working fan.
How Often Should You Change a Range Hood Filter?
There isn’t one schedule that fits every kitchen. How often you cook, what you cook, and whether your hood vents outdoors all make a difference. Frequent frying or high-heat cooking creates more grease than occasional low-heat cooking, so the filter may need attention sooner.
Check the filter regularly rather than waiting for a smell or airflow problem. If it looks greasy, feels sticky, or the hood seems less effective, clean the reusable metal filter. For disposable charcoal filters, use the replacement interval in the manual as your starting point and adjust based on how often you cook.
- Washable metal filter: Clean it when grease is visible or airflow seems reduced.
- Disposable charcoal filter: Replace it at the interval recommended by the manufacturer, or sooner if odors persist.
- Any filter: Replace it if it is damaged, won’t lock in place, or can’t be cleaned effectively.
Common Mistakes to Avoid
- Buying by appearance alone: Confirm the model or exact measurements and attachment style before ordering.
- Assuming every filter is washable: Many charcoal filters are disposable. Washing one may leave you with a filter that looks clean but no longer controls odors well.
- Forcing the filter into place: A poor fit can leave gaps or damage the frame. Check the orientation and compatibility instead.
- Reinstalling a wet filter: Let a washable filter dry completely so moisture doesn’t remain inside the hood.
- Ignoring the second filter: A recirculating hood may have a metal grease filter and a separate charcoal filter, each with different care needs.

Frequently Asked Questions
Can I replace a range hood filter myself?
In most cases, yes. Switching the hood off, releasing the filter latch, and fitting the correct replacement are usually simple tasks. Follow your model’s instructions, and don’t reach into electrical or fan components.
How do I know what size range hood filter to buy?
Use your hood’s model number to find the specified part. If that isn’t available, measure the old filter and compare its shape, thickness, and clips—not just its length and width.
Can I wash a charcoal range hood filter?
Most charcoal filters are designed to be replaced, not washed. Check the manual for your exact model. Washing may not restore the filter’s ability to absorb cooking odors.
Why does my kitchen still smell after I replace the filter?
Your hood may have a separate charcoal filter that also needs replacing, or the hood may not be moving enough air. Check that all filters are installed correctly and that the fan and any ductwork are functioning as intended.
Do I need to turn off the circuit breaker to change a filter?
For a basic filter change, turning the hood off is usually the key step. If you’ll reach near electrical parts, the hood is hardwired, or the manual calls for it, switch off power at the breaker before starting.
Conclusion
To replace a range hood filter, identify the correct filter, remove the old one carefully, and secure the new one in the proper position. The most important detail is knowing whether your hood uses a washable metal filter, a disposable charcoal filter, or both.
Check the manual, match the part to your hood model, and keep an eye on grease buildup and lingering odors. A clean, correctly fitted filter helps your hood move air properly and keeps everyday cooking from leaving quite so much behind.
